4.4 Saving & Loading Custom Profiles

Profiles let you snapshot every detection setting for a specific film stock or scanner setup, then load the same recipe in one click.

Save a Profile

  1. Tune the panel until detection looks right on a representative image.
  2. Click Save Profile.
  3. Name it descriptively. Good examples:
    • Portra 400 — lab scans
    • Velvia 50 — home DSLR scan
    • Kodachrome 64 — mounted slides
    • Tri-X push processed (chromogenic)

Load a Profile

DustMagic Global Settings panel showing the Profiles section
The Profiles section at the top of the Global Settings panel shows the active profile, with Save Profile and Load Profile below it.
  • Click Load Profile (also in File → Load Profile) and pick your saved profile.
  • Loading a profile re-populates every slider and toggle and re-runs detection on the current image.

What’s Saved

  • Film Type
  • All sliders: Smallest Defect, Largest Defect, Max Fibre Width, Sensitivity
  • All Advanced Settings: Minimum Contrast, Texture Penalty, Focus-Based Filtering, Scratch Detection (and its sub-controls)

Detection Resolution and the current view mode follow your session, not the profile.

Updating a Profile

To revise a profile: load it, make changes, click Save Profile, and re-use the same name when prompted to overwrite.

Naming Conventions

Pick something you’ll still understand in a year. Two patterns work well:

  • By stock: Portra 400 — lab, Portra 400 — home.
  • By project: Wedding 2024 negs, Family archive 1970s slides.

Put any qualifier (lab, home, archive) at the end, not the start — it makes the list easier to scan.

Recommended Starter Set

Most users settle on three or four profiles:

  • Modern colour negs (lab) — Negatives + Conservative defaults.
  • Older slides — Slides + Sensitivity nudged right; Texture Penalty raised slightly.
  • Sharp DSLR scans — Conservative; Focus-Based Filtering off.
  • Heavy scratches — Conservative + Scratch Detection on.
